IFSTA 7th Edition Chapter Test 14

IFSTA 7th Edition Chapter Test 14 When firefighters apply water to the hot gas layer in a compartment, it will: (670) [4.3.10] increase the potential for flashover. increase the radiant heat flux from the upper layer. reduce the radiant heat flux from the upper layer. push fire into adjacent rooms. - ANSWER reduce the radiant heat flux from the upper layer. What can happen if excess steam is produced inside the structure as a result of applying water on the fire? (670) [4.3.10] Disruption of the thermal layering Increase in the potential for backdraft or flashover Transition from fuel-limited to ventilation-limited conditions Pyrolysis process speeds up - ANSWER Disruption of the thermal layering In which situation would fuel removal be a likely method of extinguishment? (670) [4.3.19] Fire in an apartment building Fire in a one-story house Grass fire Warehouse fire - ANSWER Grass fire Closing the valve on a natural gas tank to stop the emission of gaseous fuel would be an example of: (670) [4.310] fuel removal. oxygen exclusion. chemical flame inhibition. temperature reduction. - ANSWER fuel removal. When a firefighter controls doors and windows during fire attack, it is an example of: (671) [4.310, 4.3.11] chemical flame inhibition. temperature reduction. fuel removal. oxygen exclusion. - ANSWER oxygen exclusion.
